DETAILED DESCRIPTION

The following description sets forth exemplary methods, parameters, andthe like. It should be recognized, however, that such description is notintended as a limitation on the scope of the present disclosure but isinstead provided as a description of exemplary embodiments.

The present disclosure provides techniques for the user device to detectand measure one or more biometric characteristics of the user thatinclude one or more physiological states (e.g., vital signs, heart rate)while the user is viewing virtual reality content. The measuredbiometric characteristics are used to determine a criterion used torecommend virtual reality content to the user that is catered to theuser's fitness level. For example, when a user accesses the virtualreality content store, virtual reality content with a rating or scorethat satisfies the criterion are prioritized over virtual realitycontent that do not meet the criterion. Optionally, because a first userhas different biometric characteristics than a second user, a first usersees different downloadable virtual reality content than a second usersees in the virtual reality content store.

Users can selectively block use of, or access to, personal informationsuch as biometric data. A system incorporating some or all of thetechnologies described herein can include hardware and/or software thatprevents or blocks access to such personal data. For example, the systemcan allow users to “opt in” or “opt out” of participation in thecollection of personal data or portions thereof. Also, users can selectnot to provide specific information, or permit provision of some typesof data (e.g., heart rate) but not other types of data. Entitiesresponsible for the collection, analysis, disclosure, transfer, storage,or other use of such personal data should comply with establishedprivacy policies and/or practices. Such entities should safeguard andsecure access to such personal data and ensure that others with accessto the personal data also comply. Such entities should implement privacypolicies and practices that meet or exceed industry or governmentalrequirements for maintaining the privacy and security of personal data.For example, an entity should collect users' personal data forlegitimate and reasonable uses, and not share or sell the data outsideof those legitimate uses. Such collection should occur only afterreceiving the users' informed consent. Furthermore, third parties canevaluate these entities to certify their adherence to establishedprivacy policies and practices.

A physical environment (or real environment) refers to a physical worldthat people can sense and/or interact with without aid of electronicsystems. Physical environments, such as a physical park, includephysical articles (or physical objects or real objects), such asphysical trees, physical buildings, and physical people. People candirectly sense and/or interact with the physical environment, such asthrough sight, touch, hearing, taste, and smell.

In contrast, a computer-generated reality (CGR) environment refers to awholly or partially simulated environment that people sense and/orinteract with via an electronic system. In CGR, a subset of a person'sphysical motions, or representations thereof, are tracked, and, inresponse, one or more characteristics of one or more virtual objectssimulated in the CGR environment are adjusted in a manner that comportswith at least one law of physics. For example, a CGR system may detect aperson's head turning and, in response, adjust graphical content and anacoustic field presented to the person in a manner similar to how suchviews and sounds would change in a physical environment. In somesituations (e.g., for accessibility reasons), adjustments tocharacteristic(s) of virtual object(s) in a CGR environment may be madein response to representations of physical motions (e.g., vocalcommands).

A person may sense and/or interact with a CGR object using any one oftheir senses, including sight, sound, touch, taste, and smell. Forexample, a person may sense and/or interact with audio objects thatcreate a 3D or spatial audio environment that provides the perception ofpoint audio sources in 3D space. In another example, audio objects mayenable audio transparency, which selectively incorporates ambient soundsfrom the physical environment with or without computer-generated audio.In some CGR environments, a person may sense and/or interact only withaudio objects. Examples of CGR include virtual reality and mixedreality.

A virtual reality (VR) environment (or virtual environment) refers to asimulated environment that is designed to be based entirely oncomputer-generated sensory inputs for one or more senses. A VRenvironment comprises a plurality of virtual objects with which a personmay sense and/or interact. For example, computer-generated imagery oftrees, buildings, and avatars representing people are examples ofvirtual objects. A person may sense and/or interact with virtual objectsin the VR environment through a simulation of the person's presencewithin the computer-generated environment, and/or through a simulationof a subset of the person's physical movements within thecomputer-generated environment.

In contrast to a VR environment, which is designed to be based entirelyon computer-generated sensory inputs, a mixed reality (MR) environmentrefers to a simulated environment that is designed to incorporatesensory inputs from the physical environment, or a representationthereof, in addition to including computer-generated sensory inputs(e.g., virtual objects). On a virtuality continuum, a mixed realityenvironment is anywhere between, but not including, a wholly physicalenvironment at one end and virtual reality environment at the other end.

In some MR environments, computer-generated sensory inputs may respondto changes in sensory inputs from the physical environment. Also, someelectronic systems for presenting an MR environment may track locationand/or orientation with respect to the physical environment to enablevirtual objects to interact with real objects (that is, physicalarticles from the physical environment or representations thereof). Forexample, a system may account for movements so that a virtual treeappears stationary with respect to the physical ground.

Examples of mixed realities include augmented reality and augmentedvirtuality.

An augmented reality (AR) environment refers to a simulated environmentin which one or more virtual objects are superimposed over a physicalenvironment, or a representation thereof. For example, an electronicsystem for presenting an AR environment may have a transparent ortranslucent display through which a person may directly view thephysical environment. The system may be configured to present virtualobjects on the transparent or translucent display, so that a person,using the system, perceives the virtual objects superimposed over thephysical environment. Alternatively, a system may have an opaque displayand one or more imaging sensors that capture images or video of thephysical environment, which are representations of the physicalenvironment. The system composites the images or video with virtualobjects, and presents the composition on the opaque display. A person,using the system, indirectly views the physical environment by way ofthe images or video of the physical environment, and perceives thevirtual objects superimposed over the physical environment. As usedherein, a video of the physical environment shown on an opaque displayis called “pass-through video,” meaning a system uses one or more imagesensor(s) to capture images of the physical environment, and uses thoseimages in presenting the AR environment on the opaque display. Furtheralternatively, a system may have a projection system that projectsvirtual objects into the physical environment, for example, as ahologram or on a physical surface, so that a person, using the system,perceives the virtual objects superimposed over the physicalenvironment.

An augmented reality environment also refers to a simulated environmentin which a representation of a physical environment is transformed bycomputer-generated sensory information. For example, in providingpass-through video, a system may transform one or more sensor images toimpose a select perspective (e.g., viewpoint) different than theperspective captured by the imaging sensors. As another example, arepresentation of a physical environment may be transformed bygraphically modifying (e.g., enlarging) portions thereof, such that themodified portion may be representative but not photorealistic versionsof the originally captured images. As a further example, arepresentation of a physical environment may be transformed bygraphically eliminating or obfuscating portions thereof.

An augmented virtuality (AV) environment refers to a simulatedenvironment in which a virtual or computer generated environmentincorporates one or more sensory inputs from the physical environment.The sensory inputs may be representations of one or more characteristicsof the physical environment. For example, an AV park may have virtualtrees and virtual buildings, but people with faces photorealisticallyreproduced from images taken of physical people. As another example, avirtual object may adopt a shape or color of a physical article imagedby one or more imaging sensors. As a further example, a virtual objectmay adopt shadows consistent with the position of the sun in thephysical environment.

There are many different types of electronic systems that enable aperson to sense and/or interact with various CGR environments. Examplesinclude head mounted systems, projection-based systems, heads-updisplays (HUDs), vehicle windshields having integrated displaycapability, windows having integrated display capability, displaysformed as lenses designed to be placed on a person's eyes (e.g., similarto contact lenses), headphones/earphones, speaker arrays, input systems(e.g., wearable or handheld controllers with or without hapticfeedback), smartphones, tablets, and desktop/laptop computers. A headmounted system may have one or more speaker(s) and an integrated opaquedisplay. Alternatively, a head mounted system may be configured toaccept an external opaque display (e.g., a smartphone). The head mountedsystem may incorporate one or more imaging sensors to capture images orvideo of the physical environment, and/or one or more microphones tocapture audio of the physical environment. Rather than an opaquedisplay, a head mounted system may have a transparent or translucentdisplay. The transparent or translucent display may have a mediumthrough which light representative of images is directed to a person'seyes. The display may utilize digital light projection, OLEDs, LEDs,uLEDs, liquid crystal on silicon, laser scanning light source, or anycombination of these technologies. The medium may be an opticalwaveguide, a hologram medium, an optical combiner, an optical reflector,or any combination thereof. In one embodiment, the transparent ortranslucent display may be configured to become opaque selectively.Projection-based systems may employ retinal projection technology thatprojects graphical images onto a person's retina. Projection systemsalso may be configured to project virtual objects into the physicalenvironment, for example, as a hologram or on a physical surface.

The representation 170 of real environment 180includes representation 170 a of person 180 a and representation 170 bof tree 180 b. For example, device 100 a uses image sensor(s) 108 tocapture images of the real environment 180 that are passed through fordisplay on displays 120 a and 120 b. Device 100 a is overlaying acomputer-generated hat 160 d (a virtual object) on the head ofrepresentation 170 a of person 180 a for display on each of displays 120a and 120 b. Device 100 a tracks the location and/or orientation ofphysical objects with respect to the position and/or orientation ofdevice 100 a to enable virtual objects to interact with physical objectsfrom real environment 180. In this example, device 100 a accounts formovements of device 100 a and person 180 a to display hat 160 d as beingon the head of representation 170 a of person 180 a.

With reference to FIGS. 2-6, exemplary techniques for detecting userbiometric characteristics, determining a criterion based on biometriccharacteristics and using the criterion to suggest relevant virtualreality content to a user in a virtual reality content store aredescribed below. FIG. 2 depicts an example of exemplary devices 204 and206 detecting user biometric characteristics as user 202 is viewingvirtual reality content. In some embodiments, exemplary user device 204is a standalone device, such as a hand-held mobile device 206, a tablet,or a laptop. In some embodiments, exemplary user device 204 is a HMD. Insome embodiments, user device 206 is a wearable device, such as a watch.

In some embodiments, exemplary user device 204 is configured to detectbiometric characteristics based on user 202's physiological state whileuser 202 is viewing virtual reality content 210 through exemplary userdevice 204. A comfort level of the user is determined based on thedetected biometric characteristics. The comfort level is a measure of anactivity level or the activeness of the user. The comfort level is basedon the physical movement of the user and is a measure of how tired theuser is after viewing virtual reality content. For example, the userplaying a game in virtual reality that requires rigorous user activityor physical movement has a low comfort level. The user's heart rate myincrease, along with the user's breathing rate, sweat level, and/or bodytemperature. These biometric characteristics are measured by exemplaryuser device 204 or paired user device 206 (e.g., a watch, motion sensor,sweat monitor, heart rate monitor, and other input devices paired toexemplary user device 204) and used to determine the comfort level ofthe user.

In some embodiments, the comfort level is determined based on biometriccharacteristics of the user (e.g., vital signs, heart rate, bloodpressure, level of restlessness, facial expressions, gestures, and sweatlevel) that indicate how comfortable the user feels when viewing virtualreality content. For example, exemplary user device 204 determineswhether user 202 feels motion sick based on the measured biometriccharacteristics. In some embodiments, exemplary user device 204 monitorsthe user's eye movements, facial expressions, and gestures to determinea comfort level of the user.

In some embodiments, if a paired device 206 (e.g., watch, phone, orother wearable device) is used in addition to exemplary user device 204,exemplary user device 204 receives biometric characteristics detected bythe paired device 206, and exemplary user device 204 uses the receivedbiometric characteristics to determine a comfort level. In someembodiments, exemplary user device 204 stores the determined comfortlevel of the user and/or the biometric characteristics in a userprofile. In some embodiments, affordance 208 representing the userprofile is displayed in virtual reality scene 210. The affordance of theuser profile 208 is associated with user biometric characteristics thatare detected while the user is viewing virtual reality content.

FIG. 3 depicts an affordance 302 of a virtual application store that isdisplayed in virtual reality scene 210 when exemplary user device 204receives a request to display one or more downloadable virtual realitycontent (e.g., a game, a website, an application) from a virtual realitycontent store. In some embodiments, exemplary user device 204 receivesuser input 304 to access the virtual reality store while displayingvirtual reality content. In some embodiments, exemplary user device 204is configured to detect user input through input sensors, motionsensors, or finger tracking sensors. The exemplary user input includesan audio input, a gesture input, or a gaze or eye movement input. Theexemplary user input can also include a button press or a touch input ona paired device 206 that is paired with exemplary user device 204. Insome embodiments, affordance 302 representing the virtual content storeis displayed in the virtual reality scene 210 only when a request toaccess the virtual reality content store is received. In someembodiments, the affordance 302 representing the virtual content storeis always displayed in the virtual reality scene 210. In someembodiments, affordance 302 representing the virtual content store isdisplayed responsive to a specific user input.

In response to receiving a request to display the virtual realitycontent store, the exemplary user device determines a criterion based onthe comfort level associated with the user's profile is used todetermine one or more recommended virtual reality content that is theappropriate level of activity for the user. In some embodiments, thecriterion is based on the detected user biometrics, which are based on achange in one or more physiological states of the user detected whilethe user is viewing virtual reality content. The exemplary user deviceprovides the determined criterion to the virtual reality content storeto obtain relevant virtual reality content having an associated scorethat satisfies the criterion to display in the virtual reality contentstore.

In some embodiments, the virtual reality contents in the virtualapplication store have associated scores or ratings that describes theactivity and/or comfort level of the contents. For example, a virtualreality content that involves a lot of user physical activity has a highactivity level or low comfort level score, while a virtual realitycontent that is likely to cause motion sickness has a lower comfortlevel score. The virtual reality content score can be based on a singlemetric or a plurality of metrics. In some examples, the score of thevirtual reality content are based on an initial rating provided by thevirtual reality content provider. In some examples, the score of thevirtual reality content are based on crowd sourced feedback obtainedfrom a plurality of users who have interacted with the content and havegiven their consent to share their biometric data.

In some embodiments, crowd sourced biometric characteristics associatedwith a particular virtual reality content are used to provide feedbackfor the score of the virtual reality content. As discussed above, userapproval should be obtained in advance of collection of biometric data.Crowd sourced information is anonymized in accordance with variousexamples.

FIG. 4 depicts an exemplary user device 408 with a display, atouch-sensitive surface, and exemplary user interface 406 displayingaffordances of applications, including affordance 402 representing avirtual reality content store application. In some embodiments,exemplary user device 408 is a standalone device, such as a hand-heldmobile device, a tablet, or a laptop. In some embodiment, the exemplaryuser device 408 is configured to receive a request to access the virtualreality content store directly from the device user interface 406. Forexample, exemplary user device 408 receives user input 208 at a locationcorresponding to affordance 402 representing the virtual reality contentstore. In response to detecting the user input 404, exemplary userdevice 408 displays the virtual reality content store. For example, userinput 404 includes a tap, a gesture, a button press, or a press onaffordance 402 representing the virtual reality content storeapplication to access additional virtual reality content.

FIG. 5A depicts an exemplary user interface of virtual reality contentstore 532 that is displayed by an exemplary user device. In someembodiments, the virtual reality content store includes virtual realitycontent, such as games, that are accessed or purchased. In someembodiments, the virtual reality content store includes additionaldownloadable virtual reality content for existing applications (e.g.,applications already available on the device). The user device displays,as part of virtual reality content store user interface 502, anaffordance of a user profile or user account 532A and one or moreaffordances of downloadable virtual reality content, for example,affordances 506, 510, 518, and 524. The exemplary user device enablesinstalling or purchasing of downloadable virtual reality content fromwithin a currently running application and directly from virtual realitycontent store.

In some embodiments, the exemplary user device is configured to displaydownloadable virtual reality content in the virtual content store userinterface 502 according to a criterion based on biometriccharacteristics or a comfort level associated with user profile 532A. Inaccordance with receiving a request to display virtual reality content,the exemplary user device displays one or more virtual reality contentin the virtual reality content store user interface 502, wherein onlyvirtual reality content with a score meeting the criterion is displayed.In some embodiments, the user device displays downloadable virtualreality content in a virtual reality store user interface 502 wherevirtual reality content that meet the criterion are prioritized in afirst section (e.g., a “Suggested” section) and virtual reality contentthat do not meet the layout are de-prioritized in one or more differentsections, such as “Challenging” section 516 or “Relaxing” section 522.

For example, in FIG. 5A, the criterion is based on a score of threestars. Based on this criterion, the exemplary user interface displaysvirtual reality content 506 and 510, which each have a respective score(e.g., 508 and 512A) of three stars that meets the criterion. Further,the exemplary user device displays the virtual reality contentsatisfying the criterion in a prioritized section 504 (e.g., Suggestedfor you). The exemplary user device displays other downloadable virtualreality contents 518 and 524 that do not meet the criteria in lowerpriority sections 516 and 522. For example, in FIG. 5A, virtual realitycontent 518 with a score 520 of five stars does not meet the criterion.Accordingly, the exemplary user device displays virtual reality content518 in the “Challenging” section 516, which is of lower priority thanthe “Suggested for you” section 504, which has higher priority.Similarly, for example, the exemplary user device displays virtualreality content 524 with a score 526 of less than three stars in thelower priority “Relaxing” section 522 because the score 526 does notmeet the criterion.

In some embodiments, the exemplary user device is configured to providethe user with access to virtual reality content store 502 (e.g., bydisplaying the virtual reality content store) while displaying virtualcontent. The exemplary user device determines the criterion used tofilter the virtual reality content prior to receiving a user request toaccess the virtual reality content store. The user device determines thecriterion while the displaying virtual reality content and stores thecriterion in the user's profile. In some embodiments, the user devicedetermines the criterion based on user biometric characteristicsmeasured after receiving the request to access the virtual realitycontent store. For example, the user device receives a request topurchase additional virtual reality content while the device isdisplaying a virtual reality scene in a game. In such an example, theexemplary user device detects the user's heartrate within apredetermined period of time after receiving the request to purchase theadditional virtual reality object.

FIG. 5B depicts an exemplary user interface of the virtual realitycontent store 502 similar to that depicted in FIG. 5A. In FIG. 5B, theexemplary device displays the virtual reality content store userinterface including downloadable virtual reality content that isprioritized by a criterion based on the biometric characteristics or acomfort level of a second user 532B. In FIG. 5B, the exemplary devicehas determined a criterion based on a score of 4 stars, as illustratedby the scores of the virtual reality content in the prioritized section504. For example, suggested virtual reality content for user 532Bincludes virtual reality content 528 which has a score 530 that meetsthe four star score criterion. In another example, the three star score508 version of virtual reality content 506 meets the criterion of athree star score for user 532A, but does not meet the criterion of afour star score for user 532B. In some examples, a downloadable virtualreality content includes several versions with different ratings. Forexample, the three star version (score 512A) of virtual reality content510 is suggested to user 532A, while the four star version (score 512B)of the virtual reality content 510 is suggested to user 532B. FIG. 6depicts an exemplary method 600 for obtaining biometric characteristicsof a user and using the biometric characteristics to determine acriterion used to suggest virtual reality content to a user in a virtualreality content store. In some examples, the method is carried out by anexemplary user device implementing system 100, such as described above.

In the description below, method 600 is described as being performedusing an exemplary user device (e.g., device 204, 206). It should berecognized that, in other embodiments, method 600 is performed using oneor more electronic devices, such as a paired exemplary user device thatis communicatively coupled to an exemplary user device (e.g., mobilephone or laptop). In some embodiments, the operations of method 600 aredistributed in any manner between the user device and a paired secondarydevice, such as a watch. It should be appreciated that the order forperforming the blocks of FIG. 6 can be modified. Further, one or moreblocks of process 600 can be optional and/or additional blocks can beperformed.

At block 602, one or more biometric characteristics of the user aremeasured by the exemplary user device using one or more biometricsensors or input sensors. For example, the one or more biometriccharacteristics of the user include one or more physiological statessuch as the user's vital signs, heart rate, sweat levels, measure ofrestlessness, blood pressure, breathing rate, body temperature, andphysical activity level. The one or more biometric or input sensors onthe system include a motion sensor, accelerometer, gyroscope, camera, asensor incorporated into a wearable device such as a watch, heart ratesensor, and moisture sensor.

The exemplary user device measures biometric characteristics before orafter block 604, which describes the system receiving a request todisplay one or more downloadable virtual reality content from a virtualreality content store. In some embodiments, the exemplary user devicemeasures (upon receiving user permission) biometric characteristics ofthe user while the user is viewing virtual reality content. For example,the user may be playing a game that requires physical activity. Theexemplary user device measures the user's heart rate during the gamebefore a request to access new virtual reality content for the game isreceived by the device. In some embodiments, the exemplary user devicemeasures biometric characteristics of the user after the user requeststo access additional virtual reality content. For example, the exemplaryuser device receives a request to access new virtual reality contentafter the user finishes viewing a movie. In some embodiments, thebiometric sensors may detect biometric characteristics of the user afterviewing virtual reality content to determine whether the user feelsmotion sick. Accordingly, upon receiving the request for new content,the exemplary user device measures the user's biometric characteristicsto determine a criterion for displaying new virtual reality content to auser that is less likely to cause motion sickness.

At block 604, the exemplary user device receives a request to displayone or more downloadable virtual reality content form the virtualreality content store. In some embodiments, the exemplary user devicereceives the request to access the virtual reality content store toaccess downloadable virtual reality content while the user is viewing avirtual reality experience. For example, while the user is immersed in avirtual reality game, watching video content, or using an application,the exemplary user device receives user input to access the virtualreality content store from within the application. In some embodiments,the exemplary user device receives user input through an audio input,touch input, or a gesture. In some embodiments, the exemplary userdevice detects a user input comprising touching or tapping an affordanceof the virtual reality content store on the user interface of theexemplary user device.

At block 606, the exemplary user interface determines a criterion basedon the measured biometric characteristics of the user. For example, theexemplary user device obtains the user's biometric characteristics orcomfort level through the user's profile. In some embodiments, theexemplary user device determines the criterion prior to the user makinga request to access the virtual reality content store. In someembodiments, exemplary user device determines the criterion after theuser has made a request to access the virtual reality content store. Insome embodiments, exemplary user device determines the criterion basedon the determined comfort level of the user. In some embodiments, thedetermined comfort level of the user is based on the activity level ofthe user (e.g., heart rate, breathing rate, body temperature, sweatlevel, how tired the user is). In some embodiments, the comfort level ishow comfortable the user feels after viewing virtual reality content).

The exemplary user device displays only virtual reality content that hasa score that matches the criterion determined based on the biometriccharacteristics of the user. In some embodiments, the one or moredownloadable virtual reality content in the virtual reality store havecorresponding scores determined based on crowd sourced data collectedfrom a plurality of virtual reality devices that has been collected withuser consent. In some embodiments, the score of a downloadable virtualreality content is based on a comfort score determined from biometriccharacteristics that are collected from a plurality of virtual realitydevices used by a plurality of other users who have purchased orinteracted with the downloadable virtual reality content. In someembodiments, the score of the downloadable virtual reality content isdetermined from crowd sourced data that was obtained upon user consent.As discussed above, user approval should be obtained in advance ofcollection of biometric data, including data to be used to determine ascore for the virtual reality content. In some embodiments, the dataprovided by the virtual reality devices of a plurality of users is madeanonymous so that only the physiological data (e.g., the user's vitalsigns, heart rate, sweat levels, measure of restlessness, bloodpressure, breathing rate, body temperature, and physical activity level)is associated with the particular virtual reality content.

At block 608, in accordance with the exemplary user device receiving arequest to display one or more downloadable virtual reality content fromthe virtual reality content store, the exemplary user device displays,on the display, one or more affordances representing virtual realitycontent where the one or more virtual reality content that meet thecriterion are prioritized over the one or more virtual reality contentthat do not meet the criterion. In some embodiments, the exemplary userdevice displays virtual reality content that meets the criterion in asuggested section, while virtual reality content that do not meet thecriterion are displayed in a de-prioritized section. In someembodiments, virtual reality content that do not meet the criterion arenot displayed at all.

At block 610, the exemplary device displays, on the display, the scoresof the respective virtual reality content with the affordancesrepresenting the virtual reality content in the virtual reality contentstore user interface. In some embodiments, the exemplary user devicedisplays the scores of the downloadable virtual reality contentconcurrently with the respective affordances representing the virtualreality content. In other embodiments, the exemplary user device doesnot display the scores of the downloadable virtual reality contentconcurrently with the respective affordances representing the virtualreality content. In some embodiments, the exemplary user device displaystwo different versions of the same content for two different users withdifferent user profiles, where one version of the content has a firstrating, and the other version of the has a different rating.

As described above, one aspect of the present technology is thegathering and use of data available from various sources to improve thedelivery to users of content.

The present disclosure recognizes that the use of such personalinformation data, in the present technology, can be used to the benefitof users. For example, the personal information data can be used todeliver targeted content that is of greater interest to the user. Insome examples, biometric data is used to deliver targeted content basedon the user's comfort level. Further, other uses for personalinformation data that benefit the user are also contemplated by thepresent disclosure. For instance, health and fitness data may be used toprovide insights into a user's general wellness, or may be used aspositive feedback to individuals using technology to pursue wellnessgoals.

The present disclosure contemplates that the entities responsible forthe collection, analysis, disclosure, transfer, storage, or other use ofsuch personal information data will comply with well-established privacypolicies and/or privacy practices. In particular, such entities shouldimplement and consistently use privacy policies and practices that aregenerally recognized as meeting or exceeding industry or governmentalrequirements for maintaining personal information data private andsecure. Such policies should be easily accessible by users, and shouldbe updated as the collection and/or use of data changes. Personalinformation from users should be collected for legitimate and reasonableuses of the entity and not shared or sold outside of those legitimateuses. Further, such collection/sharing should only occur after receivingthe informed consent of the users. Additionally, such entities shouldconsider taking any needed steps for safeguarding and securing access tosuch personal information data and ensuring that others with access tothe personal information data adhere to their privacy policies andprocedures. Further, such entities can subject themselves to evaluationby third parties to certify their adherence to widely accepted privacypolicies and practices. In addition, policies and practices should beadapted for the particular types of personal information data beingcollected and/or accessed and adapted to applicable laws and standards,including jurisdiction-specific considerations. For instance, in the US,collection of or access to certain health data may be governed byfederal and/or state laws, such as the Health Insurance Portability andAccountability Act (HIPAA); whereas health data in other countries maybe subject to other regulations and policies and should be handledaccordingly. Hence different privacy practices should be maintained fordifferent personal data types in each country. Despite the foregoing,the present disclosure also contemplates embodiments in which usersselectively block the use of, or access to, personal information data.That is, the present disclosure contemplates that hardware and/orsoftware elements can be provided to prevent or block access to suchpersonal information data. For example, in the case of content delivery,the present technology can be configured to allow users to select to“opt in” or “opt out” of participation in the collection of personalinformation data during registration for services. In another example,users can select not to provide personal biometric data for targetedcontent delivery services, or to be used as crowd sourced feedback toupdate the rating of content. In yet another example, users can selectto limit the length of time personal biometric data is maintained orentirely prohibit the development of a baseline biometric profile. Inaddition to providing “opt in” and “opt out” options, the presentdisclosure contemplates providing notifications relating to the accessor use of personal information. For instance, a user may be notifiedupon downloading an app that their personal information data will beaccessed and then reminded again just before personal information datais accessed by the app.

Moreover, it is the intent of the present disclosure that personalinformation data should be managed and handled in a way to minimizerisks of unintentional or unauthorized access or use. Risk can beminimized by limiting the collection of data and deleting data once itis no longer needed. In addition, and when applicable, including incertain health related applications, data de-identification can be usedto protect a user's privacy. De-identification may be facilitated, whenappropriate, by removing specific identifiers (e.g., date of birth,etc.), controlling the amount or specificity of data stored (e.g.,collecting location data a city level rather than at an address level),controlling how data is stored (e.g., aggregating data across users),and/or other methods.

Therefore, although the present disclosure broadly covers use ofpersonal information data to implement one or more various disclosedembodiments, the present disclosure also contemplates that the variousembodiments can also be implemented without the need for accessing suchpersonal information data. That is, the various embodiments of thepresent technology are not rendered inoperable due to the lack of all ora portion of such personal information data. For example, content can beselected and delivered to users by inferring preferences based onnon-personal information data or a bare minimum amount of personalinformation, such as the content being requested by the deviceassociated with a user, other non-personal information available to thecontent delivery services, or publicly available information.
